Create address group (safe)

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds context beyond annotations by disclosing the dry_run=true default and safety aspect, which helps the agent understand the tool's non-destructive nature despite readOnlyHint=false.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence covering purpose and default behavior. Efficient but could benefit from structure like bullet points for clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers core purpose and safety but lacks details on return values, error handling, or how to use the confirm field. With no output schema, the agent may miss expected outcomes.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description mentions 'Defaults to dry_run=true' which is already in the schema, adding minimal extra value. No further semantic enrichment.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the verb 'create', resource 'firewall address group', and key behavior 'explicit members' and 'safe' with dry_run default. Distinguishes from sibling tools like create_address or create_policy.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool vs alternatives (e.g., update_address_group_members). The 'safely' and dry_run default imply caution but lack direct when-to-use or when-not-to-use statements.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
